    TEHRAN, Feb. 10 (Xinhua) -- Hundreds of thousands of Iranians carrying flags and banners in support of the Islamic regime celebrated the 30th anniversary of Islamic Revolution on Tuesday.

    The 1979 revolution ended with toppling the U.S.-backed regime of Shah.

    Chanting anti-U.S. and anti-Israel slogans, the Iranians swarmed Tehran's biggest square of Azadi (liberty) to mark the 30th anniversary, hailing victory in all the fields that the revolution basically aimed at, in the same voice with their leaders.

    Iranian President Mahmoud Ahmadinejad who addressed a rally in Tehran, enumerated a number of the Islamic government's achievements and enthusiastically announced that Iran has now become "a real and true superpower."

    As one of the usual theme of Iranian officials' speeches, Ahmadinejad called on the U.S. and demanded the U.S. new administration to consider Iran as a global power and to hold talks on the basis of "mutual respect."

    Iran was ready for "fair talks" with the United States, he added.

    Relations between the U.S. and Iran were severed following the revolution. But on Monday, U.S. President Barack Obama said he is "looking for openings" to start face-to-face talks with Iran.

    Washington has been trying to beef up its sanctions against Tehran for being involved in anti-U.S. coalition forces activities and for allegedly developing nuclear weapons secretly.

    Iran denied the charges and insisted that its nuclear program is for peaceful purposes only.
